In this study, synthesis of copper nanoparticles was performed using organoclay as a support to stabilize the nanoparticles. Organoclay amount was gradually increased, which had an effect on the morphology of the resultant nanoparticles. Low amount of organoclay added resulted in larger and agglomerated copper nanoparticles whereas increased amount of organoclay gave smaller sized nanoparticles.

Formation of CuO nanoparticles was accompanied with colour change (blue to yellow). These were then purified by repeated centrifugation method at 6,000rpm for 25 min. Later the CuO nanoparticles were dried in an oven at 80 C for 5 hours. Table 1 Showing the procedure for the preparation of different concentrations of M. Nigra and M. azedarach.

By surfactant free hydrothermal synthesis, CuO nano-particles with particle size below 30nm are obtained. The XRD analysis results show that monoclinic CuO-crystals were formed with particle size ranging from 14nm to 27nm. The SEM analysis shows that nano-CuO formed had an irregular plate-like shape. The FTIR results show the presence of copper as oxides. The UV-VIS-NIR result is in
